The Effect of Customer Power on Frontline Employee’s Voice Behavior : An Integrated Model
Jaewon Yoo 동중앙아시아경상학회 2016 한몽경상학회 학술대회 Vol.2016 No.07
This article develops a research model that proposes a relationship among customer power, psychological empowerment, and service employee’s voice behavior. The model also suggests that managerial openness, as a result of employee-manager interface, contributes by influencing the effect of customer power on psychological empowerment. As a result of employee-role interface, task interdependence was suggested as a moderator in the relationship between psychological empowerment and voice behavior. To analyze the data, a confirmatory factor analysis procedure using LISREL 8.5 was employed. Next, conditional process modeling is fitted to test the moderated mediation hypotheses. In this stage, the moderating effects of managerial openness and task interdependence and mediating role of psychological empowerment on voice behavior are tested with bootstrapping methods. The results showed a significant relationship between customer power and service employees’ voice behavior with establishing psychological empowerment as an intervening mechanism. Thus, customer power can be the signals of appreciation for passive and job uncontrollability to service employees. The findings also suggested that moderating role of managerial openness that weakened the negative effect of customer power on the service employees’ psychological empowerment. Task interdependence enhanced the link between psychological empowerment and voice behavior.

<P><B>Abstract</B></P> <P>The triboelectric nanogenerator (TENG) is considered as a promising auxiliary source of power for portable and wearable devices. However, the power output from previously suggested TENGs driven with biomechanical energy has been insufficient for practical applications. This study suggests the concept of a Mechanical Mediator-Assisted TENG (MMA-TENG). The proposed MMA-TENG is constructed by adding a mechanical mediator (MM), which is based on a novel mechanical gear mechanism that transforms the input motion into a more favorable form for generation, to an existing freestanding rotational TENG (FR-TENG). The addition of the MM makes the MMA-TENG capable of generating an extremely high and elongated power output despite the kinematic limitations of biomechanical movements (low velocity of ~10<SUP>0</SUP> m/s and low frequency of ~ 10<SUP>0</SUP> Hz). Driven with a single hand grip motion, the MMA-TENG can generate energy at a frequency of up to 2500 Hz and realize a strikingly high power output of up to 26 mW at an optimal matching impedance of 2 MΩ. Also, it continues to generate energy for an elongated duration of 7 extra seconds after the hand grip input motion is stopped, thereby harvesting 96 mJ of energy from 8000 cycles in total. This amount is over 1000 times of that harvested from the FR-TENG without the MM for the same input (0.084 mJ from 7 cycles). After the investigation into the output characteristics of the MMA-TENG, the principle by which such striking output characteristics are enabled with it is intensively studied through a detailed kinetic analysis. Finally, several proof-of-concept demonstrations with the MMA-TENG including a charging of a 100 μF capacitor with an extremely high charge transfer quantity of ~300 μC for a single hand grip input, and a real-time generation of 5 V DC output with a buck-boost circuit are shown. Such outstanding characteristics of the MMA-TENG are expected to greatly widen the applicability of TENGs as a potent and practical biomechanical energy harvester to aid the powering of portable and wearable electronic devices.</P> <P><B>Highlights</B></P> <P> <UL> <LI> A mechanical way to increase power output of triboelectric nanogenerator is proposed. </LI> <LI> A rationally designed gear mechanism enables high and elongated power output. </LI> <LI> From hand grip, high generation frequency of 2500 Hz and power of 26 mW is achieved. </LI> <LI> From a single hand grip motion, the MMA-TENG transfers 300 µC of electrical charges. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
